Abstract

A method, including acquiring a body cavity image and receiving first and second sets of mapping points from a probe inserted into the cavity. A first registration, having a first cumulative error value, is performed between the first set's mapping points and the image, each of the first set's mapping points having a respective first point error value, and a 3D anatomical map is generated including the first set's mapping points whose respective first point error values are less than a specified threshold. A second registration is performed between the received mapping points and the image, each of the received mapping points having a respective second point error value, the second registration having a second cumulative error value lower than the first cumulative error value, and an updated 3D anatomical map is generated including the received mapping points whose respective second point error values are less than the specified threshold.
